什么是参数传递：
例如：http://localhost:8080/sprsds/index?name=87123
@RequestMapping(value = "/sprsds/index") @ResponseBody String eat(@RequestParam("name") String name) { System.out.println("test"); return name; }
响应
get方式Url传参
|—@PathVariable 即：url/id/87123形式
|—@RequestParam 即：url?name=87123形式
@PathVariable
package com.example.demo.User; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; @Controller public class index { @RequestMapping(value = "/sprsds/{name}") @ResponseBody String eat(@PathVariable("name") String name) { System.out.println("test"); return name; } }
响应
POST方式传参
@RequestParam
package com.example.demo.User; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; @Controller public class index { @RequestMapping(value = "/sprsds/index") @ResponseBody String eat(@RequestParam("name") String name) { System.out.println("test"); return name; } }
